CyberPower RT650EI uninterruptible power supply (UPS) Standby (Offline) 0.65 kVA 400 W 4 AC outlet(s)

CyberPower RT650EI is a standby uninterruptible power supply (UPS) designed for POS terminals, kiosks and workstations. With a rated capacity of 0.65 kVA (400 W) and sealed lead–acid battery technology, it offers short-term battery backup and surge protection for kiosk computer systems, credit card machines and receipt printers. The tower form factor and compact size allow installation under desks or in other confined spaces. The unit includes four AC outlets, one USB 2.0 port and is certified to RoHS and CE standards.

Advantages

The RT650EI provides battery backup and surge/spike protection in a compact tower design that fits tight spaces. Its standby UPS topology with simulated sine wave output delivers essential emergency power to connected devices, while integrated phone/fax/modem/DSL/network protection helps guard communication lines. Built‑in PowerPanel® management software enables basic power monitoring and safe shutdown when needed.

How to use

Place the UPS in a well-ventilated, dry location that can accommodate its tower form factor. Connect critical devices (POS terminal, receipt printer, modem/router) to the AC outlets. Plug the UPS into a properly grounded mains outlet and charge the internal battery before relying on backup power. Install PowerPanel® management software on a connected computer if you require monitoring and automated shutdown features. Test the UPS periodically to confirm battery condition and expected runtime.

Recommendations

For reliable short-term backup, use the RT650EI to protect critical point-of-sale and kiosk equipment from power interruptions and surges. Avoid connecting large inductive loads or devices that exceed the 400 W output rating; for longer runtime or higher power demands, consider a higher-capacity UPS model.
